Having renewed the shower in the bathroom there still remains the problem of low hotwater pressure. Which is the best way to go do you think ? Gas or Mains pressure Hot water Cylinder ?

Neither. Get a Rinnai Infinity unit and you'll never look back. You can get them for Natural Gas and LPG. They only heat when you're actually drawing water, then they shut down completely so not using any energy = very efficient. They are mains pressure.

Califont as above.
if they work as advertised hybrid heat pump hot water and use solar pv/ big battery to heat you hot water. https://youtu.be/Is9zUPuJOWw norway and sweden have some interesting hot water cylinders

How high is the shower compared with the hot water cylinder? If they are both on the same floor, a low pressure cylinder should be OK for a shower. Otherwise find the fault (shower rose needs cleaning or pressure reducing valve needs adjusting, or blocked filter by shower, or blocked pipe or tempering valve faulty)

Gas. Rinnai.
That's it.

just be aware that if you're used to having a hot water cylinder to store linen and other stuff, you wont have one with gas, although I guess if the cupboard is already there, you'll have an unheated cupboard. We really miss ours with having gas

You can buy small cupboard heaters that will keep a cupboard at a similar temperature as what a hot water cylinder does, for a fraction of the cost. Losing the cylinder will save way more energy than the heater uses.

Can get indoor infinity units too. We're getting one because there is no convenient place outside the house to bolt an external unit to (that is in a location somewhere between kitchen and bathroom). The old HW cupboard is as it turn out pretty much in the centre of the hot water requirements, the kitchen, bathroom 1 and bathroom 2. So we get to keep a HW cupboard. Indoor unit needs a flue thru the roof though.

If you have low pressure hot and cold water supplys there are only 1 or 2 shower mixer units (in my experience) that will work properly Methven I think, also the plumber should have removed a plastic insert from the cold connection.

Now that oil & gas exploration has been banned, you will need to factor in no more gas after the current wells are empty.

That's not quite true. No *new* exploration permits are to be issued. Current mining permits remain and current exploration permits may be changed to mining permits.
"On the question of supply, Ms Ardern said there were 31 active oil and gas exploration permits, including 22 offshore.
We have changed over to gas instant hot water over 2 years ago and never looked back. Saving around $100 a month on our power bill, endless hot water and high pressure. Would never have a cylinder again.

Of course you will be paying less for your power if it isnt heating your water.
You dont say how much your gas is costing you, or the cost of installation.

Hubby is a tradie, so we paid cost for all the parts and he did the labour with a friend. With the help of a plumber it was done in around 3 hours. The gas is around $98 a tank and we go through (with up to 6 adults in the house at times( 10 tanks a year). I keep records of all our power bills going back over 10 years, the savings for us have been fantastic.

Using power can cost less if set up in the right way and right size . I have 300lt and on night rate at 12 cents kw . cost for hot water is only $24 for 4 living in house .

do you get your gas at tradie rates too. I just paid for our last deliver, $129. We were paying $99 when we bought this house ten years ago, and it's gradually crept up to a price level that is not desireable

No, that is the rate, we are with Genesis Energy here in Christchurch. At one point we were on a special rate of a cylinder a month, but found we weren't using it.
